Error: ENOENT: no such file or directory, uv_os_get_passwd

[d-xo]

I get this error when trying to run hsd in a systemd service. The error is thrown on this line.

From googling around I see some similar issues where this can occur if the user in question does not have an entry in /etc/passwd:

What's your operating system?

[d-xo]

nixos

After playing around with the systemd unit a bit more, the error seems to trigger when I enable some of the systemd confinement settings (docs here). Presumably there are some systemd switches that make /etc/passwd unavailable to the service...

I'm not familiar with nixos, I wonder if the os object has different properties in nodejs. If you can solve this please let us know or open a PR for compatibility. What version of nodejs are you running?
